2010 Lexus RX450H

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2010 RX450H.

Body SUVTransmission Automatic (AV-S6)

The 2010 Lexus RX450H is a hybrid SUV that pairs an automatic AV-S6 transmission with an engine requiring 6.4 quarts of 0W-20 API oil to deliver an EPA-rated 32 city, 28 highway, and 30 combined mpg. While the broader model complaint history from 2011 to 2023 demonstrates a trajectory of improvement—peaking at 55 grievances in 2017 before dropping to a low of just one in 2023—this specific 2010 iteration tells a different story. With 96 total owner complaints predominantly focused on the engine alongside a single recall, this model year represents a more problematic chapter in the lineage, warranting careful scrutiny from researchers evaluating its long-term viability.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2010 RX450h sits at the start of this generation, and while the federal record does not include complaint counts for 2010 itself, the target-year data shows 15 engine complaints, 7 brake complaints, and 13 crash complaints—a relatively high crash figure for a single model year. For context, the following years (2011–2015) show complaint totals ranging from 13 to 36, with no recalls until 2016, suggesting that early models like the 2010 were not subject to widespread safety campaigns but did generate a steady stream of owner grievances. The 2010 model year also logged one fire complaint, which is notable but isolated. Across the generation, the recall count is very low (only two in 2016 and one in 2019), indicating that most issues were handled through TSBs rather than formal recalls. Given the 2010’s elevated crash complaint count and the lack of recall action for that year, this is a riskier buy than later model years in the generation, which benefited from incremental improvements and fewer reported incidents.
